Yeah, I like it. I had a JD 4320 and this tractor is in a different league. I believe the MX-8 cutter is a good match. It has good HP and weight, but it is not "too big". My biggest concern, initially, was how comfortable the non-air and non-adjustable seat would be. However, while not the most comfortable seat I have been in, I have adapted to it and have no complaints.
I have had a handful of "bugs" that had to be corrected, but the JD tech traveled to the farm and fixed the problems/replaced parts. A/C hoses were connected backwards, installed a new starter, installed a new windshield wiper motor, A/C line leak.
The cab is really nice. The dust free environment is AWESOME. Sometimes, when in direct sunlight with temps 90+, it feels as if the air coming out of the vents is not as cool as it is when the temps are 80 and below. Maybe that is normal. I don't know, but the air, in these conditions, is not as cool as some other cabs I have been in and I feel it should be a little colder. However, I have yet to break a sweat when I'm in the cab, and I live in Mississippi. Maybe tinted windows would help??
One disadvantage is that the tractor/MX-8 combo is harder to load on my trailer. However, I realize that I have the wrong type of trailer (a low boy with exposed fenders instead of a deck over). Also, I am always leaving tire tracks (and occasional ruts) on the grass and dirt. This was something I almost never worried about with the 4320 and R4 tires. You have to watch where you drive with this tractor if you want smooth areas for the lawn mower or other vehicles. All 4 tires are loaded.
I looked at the Kubota 7060 as well, but the JD, equipped comparably, was $2k cheaper. Plus, my nearest Kubota dealer is an hour away, and the JD dealer is 20 minutes away.
Overall, I like the tractor very well. I really like the increased HP, pulling power with my 8ft disk, a/c, and dust-free environment. It I was to do everything over again, I would make the same decision and buy the 5075E for my situation.
